Hi All,
I am using Enterprise Library in my Winform application in .Net and Oracle is my database.
I want to implement connectino pooling in my application.
My conenction strign is similar to one given below

<connectionStrings>
<add name="MyName" connectionString="user id=MyID;password=MyPassowrd;data source=(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = MyHost)(PORT = 1234))(CONNECT_DATA = (SID = MySID)))" providerName="System.Data.OracleClient"/>
</connectionStrings>

To implement connection pooling, will this be a configuration change or a C# code change.

Please advice the best possible solution.

Happy Coding
